  • This paper presents a method of synchronous rectifier(SR) for improving the efficiency in DC/DC converter. The proposed method is used push-pull topology on primary as a single winding self driven synchronous rectification(SWSDSR). Specially, this method can improve efficiency to turn on SR switch during dead time. Finally, the simulation and experimental results will be given to show comparison and analysis on the efficiency between self driven synchronous rectification(SDSR) and SWSDSR method.

  • Single winding self driven synchronous rectification(SWSDSR) scheme is based on an additional winding in the power transformer (auxiliary winding). It allows for maintaining the synchronous rectifiers on even when the voltage in the transformer is zero, which is impossible to do in traditional self-driven approaches. Its technique is verified to improve the efficiency by experiment. In this paper, there are compared self driven synchronous rectification(SDSR) with SWSDSR about the efficiency
